Access U.S. number portability data from the only authorized source
Our nation relies on connectivity. Companies require access to data regarding our nation’s nearly 1 billion telephone numbers to perform vital day-to-day operations, such as routing, rating, billing and telecommunication network maintenance. With millions of businesses and consumers switching Service Providers each year, accessing the most recent number portability data is critical.
The Number Portability Administration Center (NPAC) is the authoritative source for phone number porting information for virtually all U.S. telephone numbers, including wireless, wireline and Voice over IP Providers (VoIP). NPAC data can be accessed for very specific uses and only qualified businesses and organizations are authorized to receive the data or derived data.
